本文分析了活塞式压缩机的进排气过程;介绍了计算进排气过程的压力损失和计算压缩效率的方法;论证了采用经验公式法计算机械效率的优点,并以实际压缩机为例,进行了验证性计算;阐述了提高效率的途径。
In this paper, the process of inlet and exhaust of piston compressor is analyzed. The method of calculating the pressure loss and calculating the compression efficiency during the intake and exhaust process is introduced. The advantage of using empirical formula method to calculate the mechanical efficiency is demonstrated. Taking the actual compressor as an example, The verification calculation is carried out and the ways to improve the efficiency are expounded.
